When installing collective.contentleadimage, following error occured:
ComponentLookupError: (<InterfaceClass plone.app.viewletmanager.interfaces.IViewletSettingsStorage>, '') 

As Josh quotes here http://ifpeople.wordpress.com/2009/02/11/iviewletsettingsstorage/

the solution is to clear and rebuild the catalog.

ZMI -> portal_catalog -> TAB "Advanced" -> CLICK "Clear and rebuild"
